Notebook webcams are very popular notebook accessories that allow the notebook user to see the person with whom they are speaking. They are also used as video cameras that take pictures. Businesses use webcams for videoconferencing as real time images of conference members can be seen for a more meaningful business meeting. The video camera feeds images to a computer trough a USB, Wi-Fi, or Ethernet, making notebook webcams popular tools for security surveillance in day care centers and elsewhere. One of the most popular uses for webcams today is for recording social videos for websites like You Tube. Another popular use is to see and be seen by friends and family around the world through Web-based phone companies such as Skype.
Webcams are frequently used as security cameras. Company personnel may monitor multiple monitors for sound and movement in banks, museums, places of business, and in other places. If sound or movement is detected, the video camera begins recording and then saved to the computer. Some home and business security systems are capable of e-mailing a notice to the webcam owner or administrator to notify the person that suspicious activity has been found. There have been many cases in which images of intruders have been given to the police to aid in the capture and arrest of burglars.
Many quality notebook webcams can be purchased online. Special webcams are made to fit a notebook properly and to stay in place while they are used. One important feature to look for when buying a new webcam is the design of the equipment. Some webcams can be attached to a tripod, while others have a base that swivels. Universal clips are on many good brands that can be used on a laptop or desktop because the clips can be attached to any type of screen. Older models often had a round eyeball shape, but more modern styles are usually rectangular in shape and look a lot like a camera. The instrument should allow the user to tilt the camera for various types of shots.
A webcam is only as good as the picture that it provides, so it should have software that allows you to adjust the photos. High-definition webcams must be used on notebooks that meet the requirements for this type of video camera. The computer may slow down or freeze up if a high-def webcam is placed onto a notebook that cannot handle it. To solve the problem, the notebook’s resolution needs to be reduced. HD video should be at least 1,600 pixels by 1,200 pixels, and SD video should be at least 640 pixels by 480 pixels. The frame rate is another important consideration before making a purchase since it determines how quickly the webcam captures and plays video.
Many notebooks have a microphone, but if not, a webcam with a built-in microphone is a necessity. Most webcams have a built-in microphone, and some of them are sold with a headset that is used for sound. Speed is always an issue with Internet communication, and if the computer’s Internet connection is slow, video may be choppy and difficult to view. High-bandwidth DSL or cable Internet connections are best for streaming video. A webcam that is compact is ideal for anyone who plans to take the webcam along with them as they pack up their notebook to take along. Many webcam brands are sold with warranties that cover damage during travel, and this is an important feature to look for if the equipment will be moved frequently. Mac users need to be sure to purchase a notebook webcam that will work with their computer. Models are available that are compatible with different types of notebooks.
